APPARATUS IMPREGNATING LIQUIDS WITH CARBONIC ACID OR OTHER GASES.

To all whom it may concern:

Be it known thatv I, ANDERS ANDERSEN Pmns'ror'rn, manufacturer, citizen of the Kingdom of Denmark, Frederiksberg Alle,

have invented certam new and useful Im provements in Apparatus for Impregnating Liquids with Carbonic Acid or other Gases,

. of which the following is a specification.

My invention relates to an improved apparatus by which the liquid and the -,carbonic acid are supplied to'the bottom of a closed impregnating chamber, which is provided with perforated partitions arranged] at suitable distances apart across the chamber, and through the perforations of which partitions the liquid and-the carbonic acid ascend in such a manner that the carbonic acid expels the air contained in'the liquid,

and that said liquid. is saturated with carbonicacid, whereupon the impregnated and saturated liquid may be discharged from the top of the chamber. When however in such apparatus, only small quantities are discharged,'and the supply of carbonic acid to the apparatus is correspondingly diminished, it happens that the carbonic acid flows through portions only of the liquid contained in the impregnating chamber, be-

cause the carbonic acid ascends through portions onl of the partitions; or, if the apparatus s opes, through only one side of the apparatus so that the air is not completely expelled from the liquid and consequently said liquid is not completely saturated with carbonic acid. Said drawback is avoided by the resent invention according to which the per orated partitions are of such a shape that the ascendlng carbonic acid is caused to of the liquid 0on flow through all parts tained in the chamber whether the vsupply of carbonic acid is large or small, so that'jnf all cases the liquid will be fully saturated.

with carbonic acid. This result is obtained by making-the partitions of the impre'g'nating chamber gable, or roof-shaped andby only perforating one half or about onehalf of'each of said partitions, and by arranging" manner-that in the said partitions in such a full height of the chamber a perforated part same zigzag course during their passage through said chamber and that consequent y residing at No. 62 Copenhagen, Denmark,

The apparatus consists of a narrow and relatively high closed impregnating chamher a to' ,which the liquid to be impregnated is supplied from a higher arrangedv liquidreservoir 1; through a pi e 03 provided with a valve 0, which pipe de ouches in the bottom- 0f the chamber. The carbonic acid is supplied to the chamber a from a reservoir A through a pipe 6 havin a a controllin valve 7 therein, said pipe 6 g ing connecte A discharge chamber 9 isafranged directly over the impregnating chamber a and isconnected to said chamber a by a pipe h the impregnated l1qu1d from the chamber 9 can flow to the bottling apparatus through a pipe 11 proe the air expelled from the lmpregnated liquid andthe quantity of carbonic acid necessary for the filling of the space in the liquid reservoir 6, from which the liquid is taken, flow to the top of said liquid reservoir through a vertical pipe 7' leading from the top of said chamber 9.

The lmpregnating chamber. is provided from bottom to top with suitably-spaced gable, or roof-shaped artitions is, arranged one above anotherh (line half or wing of each of said partitions is solid or imperforate whilethe' other half or wing is perforated (Fig. 2) .Thep'artitions are arranged throughout the entire extent of the chamber insuch a mannenthat the perforated wing of=eachi partitiomdirectly overlies the nonperforated wing'of 'thenext lower.- partition, while thenon-perfOrated-wing of each partition directly overlies the perforated wing of the next lower partition, so that the asliquid currents :are' caused to follow the same zigzag course during their passage through said chamber. Consequently all portions of said liquid come in contact-with the carbonic acid whether the supply of carbonic acid is large or small.

' When the liquid reservoir 6 is emptied it a vided at its top with a funnel s and at its ries of fine holes 3 bottom with a cock 1'.

The reservoir m is in free communication at its bottom with a cylindrical chamber 2? the lower part of which is connected to the top of the liquid reservoir 6 by a pipe u provided with a valve 4. The offset upper end of an open-ended vertical ipe '0 is arranged centrally in the cham er t which pipe passes through one side of said chamber and is provided with a valve 3, the lower eiid of the pipe debouching in a depression in the bottom of the liquid reservoir 6. Between the pipe o and the wall of the chamber t a funnelhaped partition w is arranged, which is provided with annular se- The operation of lows :--It is supposed-that the reservoirs b and m are filled and that the valves 4 and 3 of the pipes u and 'v are closed.

the chamber a. Then the valve 6 is opened. The carbonic acid ascends together with the liquid through the chamber a,

expelled air and the superfluous carbonic acid fiow through the pipe 7' into the reservoir b and fill the space in said reservoir from which the liquid is taken. .The impregnated liquid flows to the bottling apparratus through the pipe i, when the valve 5 b is emptied the valves 0' and e are closed and the valves 4 and 3 of the pipes to and 0 opened. I Through .pipe '0 liquid from the supply reservoirm will then How to the liquid reservoir b, and the air and the carbonic acid contained in said reservoir will be forced into the reservoir m'through the pipe 10 and the holes y of the partition w, through which holes said air and carbonic acid will ascend in the shape of a cylindrical or tubular body through which the liquid is caused to pass in flowing t0 the pipe 4), and consequently said liquid will be partially impregnated with the {ascending carbonic acid. The carbonic acid which is not absorbed by the liquid and the'air collect the supply reservoir where said mixture due to its different specific gravities separates in such a mannerthat at the top air mixed with a small quantity of carbonic acid and below carbonic acid mixed with a small.

The pipe 0 is provided with a non-return valve 2, through which thecarbonic acid, stored in' said pipe below said valve, is supplied to the impregnating chamber a,=when liquid is supplied to the reservoir m'so that said carbonic acid is used again together with fresh carbonic acid. For the above purposes the pipe 0' debouches at some distance from the to of the reservoir m while the pipe '7) leads rom the top of said reser- V011.

Before beginning operations the air discharge-controller g is filled with liquid and the valve of the funnel liquid is discharged in drops and replaced by the air supplied through the pipe p from the reservoir m. Of'course the air discharge can be fully controlled by suitable adjustment of the cock 1', and the air can be discharged in a quiet manner.

When the air discharge-controller q is emptied the valve 8 of the pipe p and the cock 1' are closed whereupon the valve of the funnel s is opened and fresh liquid supplied to the controller.

By the improved apparatus the following new technical effects are obtained :-The liquid is fully saturated with carbonic acid whether the supply of carbonic acid is large or small so that the liquid always will be completely impregnated. The liquid can be impregnated by a much lower pressure than hitherto, as the shape and the arrangement of the perforated partitions cause all parts.

of the liquid to come in contact with the carbonic acid. The air expelled from the liquid can be discharged without carrying away considerable quantities of carbonic acid. The liquid is partially impregnated by the superfluous carbonic acid during its passage to the liquid reservoir.

Partitions as described can of course be used by all kinds of impregnating apparatus, in which liquid and carbonic acid ascend together through a closed impregnating chamber from the. top of which the impregnated liquid is discharged.
